Conflict between Spotlight and DEVONsphere Express

I can’t seem to get Spotlight to show contacts that DSE does and that are there.
Also having problems with mail searches with Spotlight. DSE better.
Wondering if indexing is dependent on one another and if there could be a conflict.
I get better results in DSE than in Spotlight.
Thanx

DEVONsphere has its own index and only uses Spotlight plugins for unknown fileTypes.

Thanks

Spotlight’s indexing of contacts is actually quite limited, DEVONsphere Express is indexing almost all information of contacts.
